Do EKGs detect ARVD (arrhythmogenic right ventricular dysplasia)?

And if not, is there a surefire way to detect this disease?

90% of individuals with ARVD have some EKG abnormality. The most common EKG abnormality seen in ARVD is T wave inversion in leads V1 to V3. However, this is a non-specific finding, and may be considered a normal variant in right bundle branch block (RBBB), women, and children under 12 years old.

RBBB itself is seen frequently in individuals with ARVD. This may be due to delayed activation of the right ventricle, rather than any intrinsic abnormality in the right bundle branch.

The epsilon wave:

The epsilon wave (marked by red triangle), seen in ARVD.

The epsilon wave is found in about 50% of those with ARVD. This is described as a terminal notch in the QRS complex. It is due to slowed intraventricular conduction. The epsilon wave may be seen on a surface EKG; however, it is more commonly seen on signal averaged EKGs.

Ventricular ectopy seen on a surface EKG in the setting of ARVD is typically of left bundle branch block (LBBB) morphology, with a QRS axis of -90 to +110 degrees. The origin of the ectopic beats is usually from one of the three regions of fatty degeneration (the "triangle of dysplasia"): the RV outflow tract, the RV inflow tract, and the RV apex.

Signal averaged ECG:

Signal averaged ECG (SAECG) is used to detect late potentials and epsilon waves in individuals with ARVD.  (+ info)

i was told today that i have dysplasia. my dr. said that she had already told me this, but i do not recall her ever mentioning this. she told me that it is now more mild than it once was about 6 months ago. she also mentioned something about an ascus? i'm not too sure what that is either. i was diagnosed with hpv also when i went and got this check up that apparently showed i have dysplasia. i would just like some information about this, can anyone explain to me what the dysplasia and also what an ascus is? thanks.

Most laboratories in the United States use a standard set of terms called the Bethesda System to report test results. Under the Bethesda System, Pap test samples that have no cell abnormalities are reported as "negative for intraepithelial lesion or malignancy." Samples with cell abnormalities are divided into the following categories:

ASC—atypical squamous cells. Squamous cells are the thin flat cells that form the surface of the cervix. The Bethesda System divides this category into two groups:

1.ASC–US—atypical squamous cells of undetermined significance. The squamous cells do not appear completely normal, but doctors are uncertain about what the cell changes mean. Sometimes the changes are related to human papillomavirus (HPV) infection (see Question 13). ACS–US are considered mild abnormalities.

Learning more about your HPV infection will help you communicate better with your doctor…

Knowledge is power!

I wish you well.  (+ info)


What is dysplasia? Can you get it by not having sex? How do you explain to your partner that pap smears should be about every year... is that correct? When you go into the doctor regualarly to get checked, does it mean your looking for trouble.... I thought you should always have a test done every so often even if not sexually active.

Dysplasia is just a description for irregular cellular growth on your cervix. While you CAN get it without having sex, it is more commonly caused by HPV which is contracted through sexual intercourse.

There's nothing to explain to your partner. Your body is NONE of his business!!
Going in for an annual pap smear is just as important as an annual physical or dental exam.
It does NOT mean that you're looking for trouble or that you're expecting to find either dysplasia or other STD.
It's just one more way for YOU to take care of YOU because no one else is going to do it for you.

11 years ago, I went in for my annual pap (skipped 2 years) and ended up with full-blown cancer. If I hadn't gone in for a check up, I'd have died.

So YES -- to care for yourself -- you should go in annually or as often as your doctor recommends, especially if you're sexually active.
But even if you've never had sex, you can still get cervical (or uterine or ovarian or vaginal) cancer because cancer doesn't CARE whether or not you're sexually active.
And 30% of all cervical cancer cases are NOT related to HPV...so you should get checked no matter what.  (+ info)

What does a symptomatic supra ventricular rhythem disturbance mean?

I've had to wear a 24 hour ECG monitor to pick up evidence of a symptomatic supra ventricular rhythm disturbance, but I do not know what this mean? Can any one help? Really not sure what supra ventricular rhythm disturbance is!!

"supraventricular" means that the rhythm originates above the ventricles, the main pumping chambers of the heart.

Symptomatic means that it causes you problems, such as dizziness, shortness of breath, etc.  (+ info)

What happens when the cervical dysplasia is gone but the high risk hpv is still present?

I was diagnosed with low-grade cervical dysplasia a while ago and following my most recent test I was told that I no longer had the dysplasia but the high-risk hpv that caused it was still there... Does this mean that cervical dysplasia could come back? And is it possible that the hpv could ever go away?

Yes, if you still have HPV present, then you could have a recurrence of cervical dysplasia. This mean you need to have regular Pap smears to monitor your progress.

Most women clear their infection eventually. But some women's infections persist indefinitely. I don't know which category you're in, but you will have to take a wait-and-see approach. In the mean time, you should take good care of yourself. Don't smoke (smoking is linked to greater risk of dysplasias), eat healthy and exercise so your otherall health and immune system are working well.  (+ info)

What is the difference between hyperplasia and dysplasia- and can anyone give me a reference for it?

I can't seem to find a book or journal article that specifically defines the difference between dysplasia and hyperplasia- any help would be much appreciated!

Hyperplasia is a general term referring to the proliferation of cells within an organ or tissue beyond that which is ordinarily seen

Dysplasia is a term used in pathology to refer to an abnormality of development.

Hyperplasia = excessive normal cells which are benign.
Dysplasia = excessive abnormal cells which can become malignant.  (+ info)

What kind of Ventricular fibrillation is not dangerous or life-threatening?

What kind of Ventricular fibrillation is not dangerous or life-threatening? That's allowed to live with it with a simple pacemaker (not ICD) to pace it out when it happens.

all v-fib is life threatening, maybe you mean atrial fibrillation, that is commonly treated with a pacemaker if cardioversion is unsuccessful and the heart rate is too low.   (+ info)

How long does it take for moderate cervical dysplasia to turn into cancer?

I have moderate cervical dysplasia and need a LEEP procedure done. I am a single mother of 4 and can't come up with the $500 that our local clinic is charging for the procedure. How long can I safely wait before this gets worse and turns into cancer?

You really should get treatment, but In also honesty, it's pretty safe to wait.

Moderate dysplasia only has about a 5% chance of becoming cancer ever, and usually it takes about 10 years for dysplasia to become cancer. Moderate dysplasia can progress to severe dyplasia quite quickly, but left untreated for a year, severe dysplasia only has about a 3% change of becoming cancer.

Doctors often wait to treat moderate dyplasia in young women (like under 20) because many fight it off on their own. Also in pregnant women, most doctors would not treat moderate dysplasia until after the baby is born.

They did this clinical trial at Johns Hopkins where they followed women with severe dysplasia for 15 weeks without treatment. They figured 15 weeks was a safe period to just observe and do nothing.

So, save up because eventually you are probably going to have to treat this. But I'd say you can wait several months without worries.  (+ info)

How often after being cleared of cervical dysplasia should I be getting pap smears?

I have had cervical dysplasia twice. Once when I was 22 and again when I was 26. After this last time I had cryosurgery and was cleared of the dysplasia. I am curious about how often I need to be going back for pap smears. I heard that I should be going back more than just once a year but my doctor did not mention when I need to return.

It depends on how severe your dysplasia was. Different classes advance at different levels. Most people with cervical dysplasia get pap smears once or twice a year, but severe dysplasia may have to be watched more closely, even quarterly or monthly. Once you have 2-3 clear pap smears, you're fine to go once a year. Call your doctor to find out when you should go back.  (+ info)
